US Treasury Securities Yield Curve for June 11, 2018

The US Treasury Yield Curve show the current yield of the full
range of securities issued by the US Treasury, from One Month Treasury Bills to 30 Year Treasury Bonds. It is considered by experts that a “normal” yield curve, where every security
with a longer maturity has a yield greater than all securities with a shorter maturity, is the sign
of a growing economy.

US Treasury Securities Yield Curve for November 28,2006

An “inverted” yield curve, where US securities with
shorter maturity have yields greater than some securities with a longer maturity, is a flashing red sign indicating recession ahead.

usgovernmentspending.com now shows the new numbers for total FY 2018 total outlays and receipts on its Estimate vs. Actual page.

The Monthly Treasury Statement includes "Table 4: Receipts of the United States Government, September 2018 and Other Periods." This table of receipts by source is used for usgovernmentspending.com to post details of federal receipt actuals for FY 2018.

This FTS report on FY 18 actuals is a problem for usgovernmentspending.com because this site uses Historical Table 3.2--Outlays by Function and Subfunction from the Budget of the United States as its basic source for federal subfunction outlays. But the Monthly Treasury Statement only includes "Table 9. Summary of Receipts by Source, and Outlays by Function of the U.S. Government, September 2018 and Other Periods". Subfunction amounts don't get reported until the FY20 budget in February 2019. Until then usgovernmentspending.com estimates actual outlays by "subfunction" for FY 2018 by factoring subfunction budgeted amounts for FY18 by the ratio between relevant actual and budgeted "function" amounts where actual outlays by subfunction cannot be gleaned from the Monthly Treasury Statement.

Final detailed FY 2018 actuals will not appear on usgovernmentspending.com until the FY 2020 federal budget is published in February 2019 with the actual outlays for FY 2018 in Historical Table 3.2--Outlays by Function and Subfunction.
